Final answer:
Maye's daily caloric intake of 18,000 kcal far exceeds her weekly expenditure of 12,600 kcal, suggesting an energy surplus that would likely lead to weight gain unless there's a mistake in the numbers provided.
Step-by-step explanation:
If Maye is consuming 18,000 kcal a day and her total weekly energy expenditure, which includes voluntary activity, thermic effect of food, and basal metabolic rate (BMR), is 12,600 kcal, we can determine which statements are true regarding her energy balance. Firstly, Maye's daily energy consumption is unusually high at 18,000 kcal—this might be a typo since an average woman's caloric intake is much lower. However, taking this number at face value, if we multiply this daily intake by 7 days, we get a weekly intake of 126,000 kcal. Her weekly energy expenditure is said to be only 12,600 kcal.
When we compare weekly intake with expenditure, it is apparent that Maye's caloric intake vastly exceeds her expenditure. This would result in a significant energy surplus, which, over time, would lead to weight gain unless there is an error in the figures provided. The thermic effects of food, physical activity, and BMR do not equate to her total energy intake, indicating an imbalance. Normally, the metabolic rate is the amount of energy consumed minus the amount of energy expended by the body. BMR is a significant portion of this, generally accounting for about 70% of total energy expenditure. Physical activity and the thermic effect of food make up the remaining 30% of total energy expenditure.
